“Melodies of nature are more mysterious, but one will hear them if he in tune with the rhythmic sense that posses”

Nature is the best teacher

Anyone know? the fact of being the best critic of this Nature enabled man to discover many things.

Whenever we are inspired by nature, it is the ultimate inspiration because our perspective and perceiving of this nature’s true image are then understood and implemented. Maybe our discoveries are due to this mother nature, there is always a unique tune of this type which match/es nature’s song.

My Experience - Physics, and people

I was very happy to attend the public lecture in the International center for theoretical science (ICTS). I met William Bialek Theoretical Physicist who become biophysicist due to his extraordinary experience with nature and its phenomena. We know this nature is full of interesting things, but each and every living being have significant traits of physical laws. One among them " A Bat - mammals of the order Chiroptera are having sense frequency detection. Bats can detect 200 kHz cannot hear very well below 10 kHz. A bat will deliver a noisy, short solid and survey the reverberate when it ricochets back. these are some of the things William shared in his lecture.

Research, Stories, Experiences

I was a regular visitor of Indian Institute of science, at whatever point I get time. Once I was going to open lecture and a science theater play in NIAS (National Institute of Advanced Studies). Generally, the address begins at 5:00 PM with Tea and an appreciated discourse. I was late for 45 minutes. by traffic with one means. But lucky enough I got rickshaw close IISc entrance. " Stuck in rush hour gridlock for an Hour in, But God spared me with this riksha", Just said to myself. The occasion was by Tom Schuch in Einstein-A Stage Portrait the best theater play, especially related to science. I appreciate that hall was full, people have a taste of science, happy to be part of the science community. play was Directed by Willard Simms. With the ordinary assembling in last corners, I just entered.

After the small disperse, I was walking around I couldn't believe myself, I was standing in front of Famous science communicator and theoretical physicist Partha Ghose, I just went and given a shake hand, with warm smile physicist asked about me, I said " Why very fewer people got Nobel prize after India independence, I can put it in this way... after CV Raman there are no physicists who received the prize, Raman, Chandrasekhar was lived in US/ other countries. " He said we will win, I had a few minutes of discussion with Partha Ghose, which was my great experiences in IISc.

Below is the Photo with Partha Ghose.

How to live longer? Physics perspective of this biological heart.[the analogy with machine & heart]

In this massive place of living systems, Homo sapiens emerged into a pioneer in technological revolutions since from early ages. It’s the technological optimism. We are at this age where we are into bionics, artificial intelligence, much more. due to the much more complex understanding of this nature made us to clearly understand the neutrons to neurons in our brain, as we are also running towards other planets, happen to see extra-planetarily voyages in future. To know the universe better.

One of the keen thought emerged within me, it’s how long we enjoy these things? can we break that barrier of death and diseases in future? Can the man win himself in preventing him from aging? Yes, why can’t we live forever? These are somethings which are challenging questions which are running through my mind. But in reality, I’m not saying the man can become immortal. But at least live longer with healthful life.

Let me go further, what is aging actually? is that only changes in physical appearance, changes in biological structure? Truly, Ageing is the process of growing old chronologically, it’s the normal process occurs to all living bodies. We can say a functional state of the living organism changes gradually when our age increases. Even the organs and organ systems show different rates of decline. The cell dies, the effectiveness of our metabolism rate decreases [ I will share some posts about the thermodynamics of human metabolism in my next post], weakening of nerves system, finally we become like neonate, I wonder Indian knew this as Kala Chakra. Human Cycle of birth and death. Growing old and person becoming the man of wrinkles in his bodies, a skin becomes as soft as babies’ skin, I visit old age houses they literally become small babies, just to add the point, please take care of elderly senior citizens, they are like small kids.

The fabric of Space-Time [astrophysics]

What is the best gift of modern physics?

Modern Physics has given the most valuable asset to the world of science. Principles that are used to describe our nature are limited. many laws are being stated and few of them succeed in proving them theoretically and sometimes experimentally, few are proved wrong.

One such curious concept read over decades, it’s also a mind-boggling concept. It is space-time. let’s see what I can say about it.

Do you know about space?

Space which is 3-Dimensional or multidimensional quantity along with planes in their curves [space-time fabric], entities will be much complex. Few people have believed that double slit experiment of physics leads to the wave nature of light, So usual science and its thoughts transformed then.

Space is the boundless three-dimensional extent in which objects and events have relative position and direction. Physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime.

space is everything in the universe beyond the top of the Earth’s atmosphere – the Moon, where the GPS satellites orbit, Mars, other stars, the Milky Way, black holes, and distant quasars. this statement defines space, which is rather part of the universe, not to consider as a physical quantity.

What about time? Good time, bad time

Time is a fascinating thing in this universe, is that time what that clock shows? or time is beyond our imagination? research says, In the beginning of time there was a singularity, where our time started. but the concept of time breaks the laws of physics. many contradictory statements are noticed to say whether the time is absolute or time is relative. but anyway modern physics and its triumph in theoretical research declared time as a non-absolute quantity.

Time and space is a continuum, we don’t have proper evidence to say time is universal, In other words, since there is no universal time. we have no time, which we can synchronize clocks. In this real world, what we also call a macroscopic world, here it’s very difficult to notice.

What is Light?

Light is more mysterious thing in-universe…its source might be difficult to tell, a form of energy. ..to all living beings, without light, no life, no sight, no evolution may be in any part of the universe. light has got a most significant role in our universe, without which evolution couldn’t be possible.

In India, we celebrate the festival of light called Deepawali / Diwali.One of the major festivals of Hinduism, it spiritually signifies the victory of light over darkness, good over evil, knowledge over ignorance, and hope over despair.

The name of festive days, as well as the rituals of Diwali, vary significantly among Hindus, based on the region of India. In many parts of India, the festivities start with Dhanteras (in Northern and Western part of India), followed by Naraka Chaturdasi on the second day, Deepavali on the third day, Diwali Padva dedicated to wife–husband relationship on the fourth day, and festivities end with Bhai Dooj dedicated to sister–brother bond on the fifth day. Dhanteras usually falls eighteen days after Dussehra.

Understanding depth of Einstein’s Field Equations

I never attempted these equations until I make my own particular scientific ways to deal with the level of numerical ability of science required for this, I used to think like this when I was the student. I recommend readers of my blog to read Einstein’s field equations, but before understanding them, know that the field conditions need higher arithmetic… folks once consider the photoelectric impact, that was most prominent disclosure which Einstein got Nobel prize, but now school children discover that and they comprehend the fundamentals. Same way the field condition needs fundamentals (those we don’t think about in school) They are in harmony with the complex understanding of the universe.

learning Einstein’s certain speculations give more creative energy to the mind, I myself-got comprehend when I endeavored to find out about the Einstein exceptional hypothesis of relativity.

The Einstein field conditions (EFE) or Einstein’s conditions are an arrangement of 10 conditions in Albert Einstein’s general hypothesis of relativity which depict the essential collaboration of attraction because of spacetime being bent by issue and Relativity. In the first place distributed by Einstein in 1915 as a tensor condition, the EFE compare nearby spacetime ebb and flow (communicated by the Einstein tensor) with the neighborhood Relativity and force inside that spacetime (communicated by the stress– relativity tensor).

Like how electromagnetic fields are resolved to utilize charges and streams by means of Maxwell’s conditions, the EFE are utilized to decide the spacetime geometry coming about because of the nearness of mass-Relativity and direct force, that is, they decide the metric tensor of spacetime for a given course of action of stress– relativity in the spacetime. The connection between the metric tensor and the Einstein tensor permits the EFE to be composed as an arrangement of non-straight fractional differential conditions when utilized as a part of along these lines. The arrangements of the EFE are the segments of the metric tensor. The inertial directions of particles and radiation (geodesics) in the subsequent geometry are then ascertained utilizing the geodesic equation. As well as obeying neighborhood Relativity force protection, the EFE lessen to Newton’s law of attractive energy where the gravitational field is powerless and speeds are substantially less than the speed of light. Exact answers for the EFE must be found under rearranging presumptions, for example, symmetry. Extraordinary classes of correct arrangements are frequently examined as they show numerous gravitational marvels, for example, turning dark gaps and the expanding universe. Assist rearrangements is accomplished by approximating the genuine spacetime as level spacetime with a little deviation, prompting the linearized EFE. These conditions are utilized to ponder wonders,

for example, gravitational waves. Similar to how electromagnetic fields are resolved utilizing charges and streams through Maxwell’s conditions, the EFE are utilized to decide the spacetime geometry coming about because of the nearness of mass-Relativity and straight force, that is, they decide the metric tensor of spacetime for a given course of action of stress– Relativity in the spacetime. The connection between the metric tensor and the Einstein tensor permits the EFE to be composed as an arrangement of non-straight incomplete differential conditions when utilized as a part of along these lines. The arrangements of the EFE are the segments of the metric tensor. The inertial directions of particles and radiation (geodesics) in the subsequent geometry are then computed utilizing the geodesic condition.

And in addition, obeying neighborhood Relativity force preservation, the EFE lessen to Newton’s law of attractive energy where the gravitational field is frail and speeds are considerably less than the speed of light.

Exact answers for the EFE must be found under streamlining presumptions, for example, symmetry. Uncommon classes of correct arrangements are frequently contemplated as they demonstrate numerous gravitational wonders, for example, pivoting dark gaps and the expanding universe. Promote disentanglement is accomplished by approximating the genuine spacetime as level spacetime with a little deviation, prompting the linearized EFE. These conditions are utilized to think about marvels, for example, gravitational waves.
